I run a stock truck muffler on my 261 that I bought from Jim Carter, and had a local exhaust shop bend a new header pipe and tail pipe that exits just below the rear bumper on the drivers side. Not too loud but not too quiet either, in my opinion it's a great sound for these old 6's.

PM me if you want to hear it.
